摘要:: 某雷达系统中射频开关在快速切换通道时偶尔会出现信号功率损耗过大的情况，导致信号衰减甚至中断。该文提出了一种基于同步触发的自动化测试方法，以实现射频开关使用前的插入损耗指标测试。通过编译的测控软件，实现了整个测试过程的自动化控制和数据采集，并将测试数据以及测试过程信息输出的报表中。实验证明，该方法可以准确地测试射频开关的插入损耗指标，进而实现对射频开关的质量检测，保证了雷达系统中的信号稳定性。

Abstract:: RF switches in the fast switching channels occasionally appear signal power loss too large in a radar system, led to the signal attenuation and evensuspension.This paper proposes an automatic test method based on synchronous trigger for the insertion loss index test before used. Through the measurement and control software, realize the automatic control of the whole test process and data acquisition,and output the test data and test process information into reportforms. Experiments show that this method can accurately test the insertion loss of RF switches,and then to detect the quality of RF switches, to ensure the signal stability in theradar system.
